“With great clarity, A New Leaf offers a sweeping and important view of today’s changing attitudes toward marijuana.”

—Amy Wilentz, author of The Rainy Season and Farewell, Fred Voodoo, a National Book Critics Circle Award winner

“Just in time: Martin and Rashidian bring us the first account of the lively new green economy that is springing up in the wake of marijuana decriminalization and legalization. This is a meticulously reported book and a firm rebuke to the continuing federal prohibition.”

—Barbara Ehrenreich, bestselling author of Nickel and Dimed

“A cogent, well-sourced and ambitious analysis of the slow decline of cannabis prohibition in the United States. . . . A piercing work of sociological reportage.”

“Nothing less than an indictment of a national disgrace—a must-read for anyone who wants to participate in the urgent conversation about cannabis legalization, drug policy reform, and the assault of the drug war on civil liberties.”

—Nadine Strossen, professor at New York Law School and former president of the ACLU

“A comprehensive look at the political and social revolution taking place that is leading to the day when marijuana will inevitably be legal in all fifty states. The authors take us on a journey to meet the people on the front lines of this transformation.”

—Dale Maharidge, co-author of the Pulitzer Prize–winning And Their Children After Them and author of Bringing Mulligan Home
